Patent DE-3140109-A1 (DE)
Title: Musical instrument with electronic sound generation
Inventor: FASSBENDER HANS PETER
IPC: G10H7/06
Filed: 1981-10-09
Abstract: To generate sound in an electronic musical instrument, it is proposed that a sound curve stored in a sound curve memory constructed as digital memory is sound-determining for all fundamental frequencies or some of the fundamental frequencies of the musical instrument by means of series scanning, the periods of the fundamental frequencies representing the frequencies of the fundamental tones. In contrast to the high number of memories required in known arrangements, only one sound curve memory is required in principle in the musical instrument proposed. Different sound characteristics can be achieved by reprogramming the sound curve memory. With a particular programming of the sound curve memory, all tones of the musical instrument exhibit the same tonal colour.

Patent DE-3203533-A1 (DE)
Title: Hydraulic cartridge valve
Inventor: HELFENSDOERFER HANS
IPC: F16K31/06
Filed: 1982-02-03
Abstract: The invention proposes a hydraulic cartridge valve (10) with an attached electromechanical displacement sensor (11), which, with a constant pressure drop, avoids scatter in the magnitude of the pressure-medium flows due to a changing angular position of the slide (17) relative to the housing (14) by means of an anti-rotation safeguard (37). A profiled portion (31) of a transmission member (29) which couples the slide (17) to a movable core in the displacement sensor (11) passes through a retention disc (32) fixed to the housing and matched in shape to the said portion. The anti-rotation safeguard (37) arranged in the cover (13) concentrically to the slide (17) holds the radial holes (21, 22, 25) of the slide (17) and the housing sleeve (14) in an optimum angular position relative to one another without taking up the limited installation space for the parts (14, 17) through which pressure medium flows directly, and is in addition of simple construction. <IMAGE>
Patent DE-3204146-A1 (DE)
Title: Method of measuring the composition and local concentration of substances at surfaces
Inventor: BOETTCHER BERNHARD DR ING
IPC: G01N21/55
Filed: 1982-02-06
Abstract: The invention describes a novel analytical method for the nondestructive measurement of the composition and local concentration of substances at surfaces. The measurement area is illuminated with infrared light of known wavelength and intensity and imaged with the aid of the reflected radiation and, for example, an infrared camera. If the incident infrared light has a wavelength at which a certain substance in the measurement area has a strong absorption, the reflected light is altered, mainly in intensity, compared with other wavelength ranges not having substance-specific absorption, and the distribution of the substance on the measurement area becomes visible. Figure 3 shows an embodiment of the method. The infrared light source used is a tunable laser (5) which illuminates the measurement area (7) via an optical expansion system. The light reflected from that point is fed via an imaging optical system (8), a narrow band filter (9), an analyser (10) to an infrared camera (11) which provides an infrared image of the measurement area. The method has hitherto been used successfully to determine the moisture distribution on the surfaces of building materials. <IMAGE>

Title: Photographic camera having an electric motor drive
Inventor: BLAETTNER DIETMAR
IPC: G03B17/42
Filed: 1982-05-08
Abstract: In a photographic camera, transporting film and cocking the shutter is accomplished by means of an electric motor. In order for the film transport, or in the case of a photographic instant camera the delivery of a picture unit, not to be executed until after the end of the exposure operation, the switching contact (22) is provided which has two pairs of switching contacts (2a, 3a; 2b, 3b) located in the motor circuit. The first contact pair (2b, 3b) projects into the region of the two pins (1d, 1e) provided on the shutter release (1), and the second contact pair (2a, 3a) projects into the region of a switching disc (6). A shutter control element (4) that can be released by the shutter release (1) initially holds the first contact pair (2b, 3b) closed until the switching disc (6) has, on the one hand, closed the electrically parallel second contact pair (2a, 3a), and the shutter control element (4) has been swivelled back into its resiliently prestressed standby position by cams (6c, 6d) arranged on the switching disc (6). The switching disc (6) has switching surfaces (6a and 6b), which are located in a depression and by means of which the switching contact (2a, 3a) is reopened and the motor is stopped. <IMAGE>

Title: Device for the thermal protection of heating elements
Inventor: JUST DIETHOLD DIPL ING
IPC: H01H37/34
Filed: 1982-07-27
Abstract: The invention relates to a device for the thermal protection of heating elements in washing machines, in order to prevent unacceptably high excess temperatures in the absence of the medium to be heated. The invention is intended to achieve the object of providing reliably effective disconnection of the heating element in the absence of the medium to be heated, with a low component cost. The object is achieved according to the invention in that a known bimetallic switch is mounted outside the container, immediately underneath the heating element which rests on the container wall in the form of a spot, and a heat-conducting metal sheet is arranged between the container wall and the bimetallic switch in order to create deliberate heat transfer. Possible fields of application are, primarily, washing machines and dishwashers as well as containers in which heating elements heat specific media and reliable protection of the heating elements and their surrounding parts against unacceptably high excess temperatures must be ensured. <IMAGE>

Title: Method for testing the speech path switching network of a telephone switching system, particularly of a telephone branch exchange
Inventor: KRAUSE RUEDIGER DIPL ING
IPC: H04Q1/24
Filed: 1982-09-28
Abstract: When the data which are necessary for reproducing each connecting path set through the switching network (KN) and which define the tested switching point and the switching matrix located in the course of this connecting path, are provided for setting up this connecting path, they are simultaneously written into an auxiliary memory and temporarily stored. When an error occurs, the content of the temporary store, together with a code which is permanently allocated to each error occurring with a particular test criterion, is in each case transferred into an error memory (FSP). The content of the error memory can be displayed on a display and/or printed out. A corresponding instruction input has the effect that the connecting path corresponding to an error event is again set and the associated test criterion is sent out. If its evaluation by the test equipment (PE) shows that freedom from errors exists, the error event registered during the first test is considered to be a random error and the error entry made with respect to the original test process is deleted. <IMAGE>

Title: Spray device
Inventor: SUTTNER WOLFGANG
IPC: B05B9/01
Filed: 1982-10-06
Abstract: In a spray device having a spray gun (10) for fluids flowing at overpressure, in particular for water for cleaning objects, having a valve insert (12) which is arranged in a pistol housing (11) and whose valve through which the fluid flows can be actuated by a manual lever (13), having a pressure hose (16) which is connected to the fluid line of the spray gun (10) at the inlet point, and having a spray pipe (20) which is connected to the outlet point, the fluid line contains a connecting device (21) which permits the spray gun (10) to be rotated about its longitudinal axis in relation to the pressure hose (16) and to the spray pipe (20). In this way, the spray gun (10) can rotate, for example, about the longitudinal axis of the pressure hose (16), which is filled with working substance, without said pressure hose also being rotated. The torques which prevent the rotation of the spray gun (10) can thus not start from the pressure hose (16) so that said pressure hose (16) can be easily assembled. <IMAGE>

Title: Circuit arrangement for failsafe monitoring of a stored-program press safety control
Inventor: RICHTER DIETRICH DIPL ING
IPC: G05B19/05
Filed: 1983-01-24
Abstract: The aim is to utilise the advantages of stored-program technology and to use commercially available stored-program control facilities without additional interfaces and devices for synchronising and comparing the program sequences of both controls. The object lies in the failsafe monitoring of the two stored-program control facilities without additional equipment expenditure and in a failsafe actuation of the press safety valves. According to the invention, this is achieved by the fact that the failsafe monitoring of the equivalence, time-shifted by a maximum of one cycle period, of the outputs (A2; A2' to An; An') of the stored-program control devices (2; 2'), which operate independently of one another, is created with the same programming by outputting certain identical program points at the outputs (A2; A2' to An; An') to the external comparators (7) of the monitoring channel and that the respective output (A1, A1') for actuating a press safety valve (5; 5') is conducted to a safety amplifier (4; 4') which must be enabled by the monitoring channel. <IMAGE>

Title: Method for the wireless transmission of the control variable in a closed control loop, and a device for carrying out the method
Inventor: HUND HELMUT
IPC: G05D23/19
Filed: 1983-03-08
Abstract: A method for controlling a variable, above all a method for controlling the temperature of a room, is described. In addition, two devices for carrying out this method are disclosed. The method is distinguished in that the control variable y or the control variable x are transmitted on at least a part of their path to the actuating element or to the controller by means of modulated IR beams. The devices for carrying out the method comprise an IR transmitting diode, which emits IR beams which are modulated corresponding to the signal output of a sensor, are received at the reception end by an IR receiving diode and are supplied, in conditioned form, to the actuating element or to the controller. The latter passes a corresponding control variable y, in a manner known per se, to the actuating element which, in the case of a room-temperature controller, is formed, for example, by the heating valve or an electrical heating apparatus.
